Description

Electronic endoscope hose seal test system

Technical Field

The utility model relates to a medical instrument processing technology, especially an electronic endoscope hose seals test system.

Background

The electronic endoscope is used as a medical product which needs frequent cleaning, soaking and disinfection, and the sealing performance is particularly critical; in the production process of electronic endoscope products, 100% sealing test needs to be carried out on the inserted hose and the incoming material of the light guide hose, and the integral sealing can be realized after the assembly is finished.

The current hose sealing test scheme is a manual single-piece test, and the test device comprises a water tank, a barometer, a silicone tube, a manual air pump and a plug. During testing, one end of the testing hose is connected with the silicone tube of the testing device, the other end of the testing hose is plugged by the plug, the testing hose is inflated to a set pressure value by the aid of the manual air pump, the testing hose is immersed into the water tank to observe set time, whether bubbles are generated is judged according to the standard, if bubbles are generated, the testing hose is damaged, and if bubbles are not generated, the testing hose is qualified. The existing test scheme has low efficiency due to single test, and high labor intensity due to the adoption of manual pump for inflation.

Disclosure of Invention

The utility model aims at providing an electronic endoscope hose seal test system that efficiency of software testing is high, intensity of labour is low to current endoscope hose leakproofness efficiency of software testing low, the not enough of intensity of labour is high.

In order to achieve the above purpose, the present invention adopts the following technical solution.

A hose sealing test system of an electronic endoscope comprises a water tank, wherein a plurality of air inlet valves and a plurality of exhaust valves are respectively arranged at two ends of the water tank, the air inlet valves and the exhaust valves are respectively connected with first sealing hoses and second sealing hoses, and the first sealing hoses and the second sealing hoses are correspondingly connected with a test hose; all the air inlet valves are arranged on the distribution pipe, and the distribution pipe is connected with an air compressor through an air supply pipe; the air supply pipe is provided with a pressure regulating valve.

Adopt aforementioned technical scheme the utility model discloses, the inspection is aerifyd to the compressed air that provides through the air compressor machine to replace artifical manual inflation, reduced intensity of labour. Simultaneously, through setting up a plurality of admission valves, discharge valve and sealing hose, every admission valve, discharge valve and two sealing hose constitute a detection group, every group corresponds and detects a test hose, so both can carry out the test of a test hose alone, also can test many test hoses simultaneously, obviously, because the test time needs pressurize 5min, and the time of coupling hose only needs several seconds or more than ten seconds about usually, so when many test hoses tested simultaneously, can show improvement efficiency of software testing.

Preferably, the pressure regulating valve is connected to the distribution pipe through a joint; the pressure regulating valve is also provided with a pressure gauge. So as to correctly display the testing pressure through the pressure gauge and ensure the accuracy of the testing result.

Preferably, the exhaust valve is fixedly connected to the side wall of the corresponding end of the water tank, and the outlet end of the exhaust valve extends out of the water tank. After the test is finished, when the test is disassembled, the gas sealed in the pipe is discharged outside through the exhaust valve, and the water in the water tank is prevented from being taken out of the water tank.

Preferably, the air inlet valve and the air outlet valve are both manual ball valves. And a complex electric control system is not needed, and the test cost is reduced.

Preferably, the distribution pipe is made of a rectangular pipe or a square steel pipe. The large-area contact with the side wall of the water tank is facilitated, and the connection reliability is improved.

Preferably, the water tank is provided with a plurality of supporting legs, the side wall of the water tank is provided with an overflow port, and the bottom of the water tank is connected with a water drain valve. The reasonable operation height can be formed under the proper condition of the water tank through the arrangement of the supporting legs, so that the operation convenience is improved; meanwhile, through the arrangement of the overflow groove, the overflow is normalized in a set area, and the purification of the test environment is facilitated.

The beneficial effects of the utility model are that, but the check of singleton, also many simultaneous inspections use in a flexible way, convenient operation, and low in labor strength, efficiency of software testing is high.
